Dean Richards says the team are determined to reverse the outcome of the league meeting when they return to St Mary's to face Southampton in the FA Cup on Saturday.
The big defender points out, however, that there was no lack of determination on New Year's Day and feels the team were unfortunate to come out with no reward for their display.
"They are all big games," reasoned Dean. "You approach the game in the same way but Saturday has become even bigger as you want to reverse the outcome - so yes it does.
"But we were up for the league game and I felt for long periods, especially second half, we looked like we were in control."
Dean's inside knowledge of the strengths of Saints match-winner James Beattie could not prevent the burly striker putting his name on the scoresheet on Wednesday, but he was quick to hand credit to his former teammate.
"He did well. He came across me so I think he was onside. Usually in those situations I try to show people outside, but his right foot is strong and I didn't want to invite him to shoot.
"Then he dragged it back inside and it was a good finish. You've got to hold your hands up sometimes and say 'good goal'.
"To be honest I felt we were creating good chances, we soaked up a bit of pressure but they didn't really get in behind us.
"Maybe we were too hell bent on winning the game and a point wouldn't have been a bad result.
"We had a couple of good chances and I think that is the difference at this level, you score first and it takes a lot of pressure off the defence."
